Image Geoanalysis: Secrets of Digital Discovery

Images have always played an important role in the OSINT analyst’s arsenal. In this article, you will find a detailed overview of the techniques and tools that will help you perform deep geoanalysis of images, opening up wide opportunities for discovering, analyzing and interpreting information that is hidden at first glance. Images are not just photos or videos. It is a powerful disclosure tool that can point to locations, people, time frames, and other important aspects. Using specialized tools and techniques, it is possible to “read” the image, identifying details that remain invisible to the untrained eye. The key to successful geoanalysis within OSINT is the ability to combine and interpret data.

Trees, buildings, shadows, bodies of water – everything can serve as a clue for the analyst. How well you identify and analyze these details will determine the success of your investigation. With the help of modern technologies and software, geoanalysis becomes even more accessible and effective. Application of machine learning algorithms, automated object recognition systems and other innovative approaches make image analysis not only faster, but also more accurate. Every OSINT analyst should understand that imagery can be critical in the data collection process. With the help of deep geoanalysis, you not only discover information, but also create more reasonable and accurate conclusions.

So, let’s start!

When Robert (@osintaclaus) posted his challenge on Twitter, it was like an invitation to an exciting intellectual adventure. The gauntlet was thrown: decode the mysterious geolocation of the image using OSINT and IMINT tools. With unwavering determination, we accepted the challenge not just as an attempt but as an expedition to prove the prowess of analytical thinking and digital research.

Through strategic skill and a well-honed analytical approach, I was able to decipher the image’s hidden geolocation — all within an hour of its publication.

My quick response to this challenge

Fast and furious, we set out on a journey to dissect the image, uploading it as the first step. Armed with persistence and a sharp eye, we combed through every pixel to find the tiniest clue that could unlock the mystery of the image’s origin.

After uploading the image of the call, we began a detailed analysis to uncover potential clues pointing to its origin. It is noteworthy that our attention was immediately drawn to the church depicted in the image. This architectural centerpiece was constructed using distinctive red brick and featured outstanding stained glass windows that elegantly embellished the building. The steeple was also tall.

Among the intricate details, we noticed that the facade of the church displayed red windows in white frames located at the top of the building. This architectural feature is consistent with the distinctive style often found in churches. Beyond its visual appeal, however, the image seemed to contain geographic features ripe for interpretation.

At a key point in the opening, we came across a bright blue sign that read “Stationsstraat”. This pointer was not just a visual element; this served as a critical clue to the location of the image. From a linguistic point of view, we understood that “Stationstraat” comes from the Dutch word “straat” which translates to “street”. This linguistic link was a strong indication of the image’s connection to the Netherlands.

Additionally, another sign in the image contained the Dutch word “uitgezonderd” which was accompanied by an image of a bicycle, which translates to “except” in English. This linguistic bridge provided a valuable context, suggesting certain restrictions or permissions in the Dutch context.
These cumulative observations, including architectural features, linguistic ideas, and cultural contexts, gradually led us to a comprehensive understanding of the location of the image.

The signs are written in Dutch.

We Googled the street name and realized that Stationsstraat is a common street name in both the Netherlands and Belgium. The spelling Stationstraat is also used.

A look at the Wikipedia results highlights the existence of many towns in both Belgium and the Netherlands that share the street name “Stationstraat”. To my surprise, this ubiquitous name found its way to about 30 cities where the corresponding image was taken. This large volume presents a significant challenge in terms of research and deduction. The need to meticulously sift through such a large number of potential locations is both frightening and exciting.

In light of Wikipedia’s findings, a strategic shift became apparent: focusing efforts on Belgium and the Netherlands. However, navigating the complex landscapes of the 30 cities spanning the two countries, all of which could potentially house the elusive Station Street, presented a major challenge. The task of singling out a particular church in this vast network was like looking for a needle in a haystack.

Recognizing the need for a more targeted approach, we turned to a proven OSINT technique: reverse image retrieval. This method promised to harness the power of technology to simplify investigations. By submitting challenge images to online search engines, I aimed to find matches or similar images that could shed light on the architectural style and details of a particular church.

The beauty of this technique was its ability to compare images to a large database of visuals from around the web. This process contained the potential for significant urban narrowing, which warranted further study. Although the task remained difficult, reverse image retrieval became a beacon of efficiency in navigating the complex streams of this puzzle.

In our quest to narrow down the location, we turned to Google Lens, an image recognition tool in the Google ecosystem. Using Google Lens, I uploaded images of the church call to the system to find matches or similar images online. This approach combined human analysis with the help of artificial intelligence, effectively advancing the investigation. The integration of traditional methods and technological innovations demonstrated the essence of OSINT in action.

After using ‘Google Lens’ there was a breakthrough as the tool successfully recognized the church depicted in the image. A further cascade of results ensured a series of church-related matches. However, to refine the search, a strategic decision was made: add “Netherlands + Belgium” to the query. This modification was intended to direct the search to churches that share a common visual similarity in both countries. The intent was to pinpoint architectural features that transcend geographic boundaries, increasing the likelihood of identifying elusive terrain. This focused approach demonstrated a combination of technological assistance and investigative finesse, epitomizing the dynamic nature of OSINT strategies.

Among the array of results, a strikingly similar image caught our eye – it matched “MariaKerk” from Wikidata. This discovery became an important milestone in the investigation. The alignment of visuals between the challenge image and the ” MariaKerk” image served as a beacon of hope, indicating a potential connection to the elusive location.
This case underscored the essence of OSINT as a fusion of inventive research and technological tools, illustrating the potential for uncovering hidden truths through unwavering determination and innovative methodologies.

Here is the full size image. We see a spire with a cross on top, red windows, large windows and the name of the street in a blue sign – all similar to the original image from the task.

We decided to search the name of the city on Google and get more information about the city. Apeldoorn is a small city in the Netherlands, located approx. 1 hour drive from the capital Amsterdam.

Then we decided to look for churches in this city.

“Catholic Directory”

We found a website that provides information about all churches in countries and cities, the result gave me 7 churches in Apeldoorn, Netherlands. Do you remember “Mariakerk”? The first result also contained the name St. Mary.

This gave me the exact location of the church.

The exact location of the church

We decided to go to the official website of the “Netherlands Cultural Heritage Agency” ( Rijksdienst voor het Cultureel Erfgoed) to try and check the availability of heritage sites in the Netherlands (Church).

The Wikipedia search also has search results for Apeldoorn church, but it is not similar to ours.

We used Google Dorks to find a church with a location and a church in the Dutch language “Kerk” on the official website of the Netherlands Heritage Agency.
